Abstract

A fiber distribution system ( 10 ) includes a fiber distribution hub ( 20, 300 ); at least one fiber distribution terminal ( 30, 100 ); and a cable ( 40 ) wrapped around a spool ( 110 ) of the fiber distribution terminal ( 30, 100 ). The fiber distribution terminal ( 30, 100 ) includes a spool ( 110 ) and a management tray ( 120 ) that rotate together. A second connectorized end ( 40 b ) of the cable ( 40 ) is held at a fiber optic adapter ( 125 ) on the tray ( 120 ). After dispensing the first connectorized end ( 40 a ) to the hub ( 20 ), an optical splitter ( 70, 130, 140 ) can be mounted to the tray ( 120 ). The splitter ( 26, 70, 130, 140, 306 ) has output adapters at which patch cords ( 50 ) can be inserted to connect subscribers to the system. The fiber distribution hub can use the same format of splitters ( 26, 70, 130, 140, 306 ). Other distributed splitter systems are provided with splicing and/or adding of splitters as needed.

First claim

What is claimed is:

1. A fiber distribution hub comprising:
an enclosure including a basepart and a cover, the basepart including a first major side, a second major side generally parallel to the first major side, a first minor side, and a second minor side oppositely disposed to the first minor side, wherein the first minor side and the second minor side extend generally perpendicularly between the first major side and the second major side;
wherein the basepart includes first and second splitter areas located adjacent each of the respective first and second minor sides of the basepart, each of the first and second splitter areas being located adjacent the second major side of the basepart, the basepart also including first and second cable management areas, the respective first and second cable management areas being located adjacent the respective first and second splitter areas, and a central channel defined between the first and second cable management areas, the central channel communicating with an upper cable termination and splice tray area, the upper cable termination and splice tray area being positioned adjacent to the first major side of the basepart;
a plurality of splitter modules located in each of the first and second splitter areas, each of the plurality of splitter modules including at least one input and a plurality of outputs in the form of adapters;
a plurality of splice trays located in the upper cable termination and splice tray area and separate from the plurality of splitter modules, each of the plurality of splice trays including integrated cable termination, wherein the splice trays each include a cable termination bracket and a pivotally mounted splice cassette for holding cable and splices, wherein cables entering and exiting the splice trays are terminated on the cable termination bracket, and wherein a riser cable or a feeder cable is connected at an outside portion of the cable termination bracket, and an opposite end of the cable termination bracket is connected to connectorized pigtails.

2. The fiber distribution hub of claim 1 , wherein each splice cassette includes cable loop storage and cable splice holders.

3. The fiber distribution hub of claim 1 , wherein the plurality of splice trays are provided in two columns, wherein the connectorized pigtails are positioned in the central channel.

4. The fiber distribution hub of claim 1 , wherein the at least one input and a plurality of outputs in the form of adapters face a front of the hub.

5. The fiber distribution hub of claim 1 , wherein pivot axes of the splice cassettes extend horizontally and transversely to the front of the hub.

6. The fiber distribution hub of claim 1 , wherein axes of the cables entering the splice trays extend horizontally and transversely to the front of the hub.

7. The fiber distribution hub of claim 1 , wherein the cable management area and the splitter area are formed together as one piece.
